Basically I tried 4 times to buy an item, with 2 different credit cards. All transactions were paid according to my card companies, they even gave me reference numbers. AO "didn't receive" any of them, they blamed my side everytime, I gave my card companies some grief and they explained they had paid.... AO had NO idea what was going on, just kept asking to try again. Customer service agents were clearly unable to offer any advice of any value for this matter. I suggested the contact their online banking company and find out why... they couldn't do that. Strongly advise you don't buy anything through this shambolic pile of trash company. Stick to Amazon.
